A teenager who was stabbed and effectively dead for nearly an hour beamed in court as he watched his two attackers being convicted.
James Bascoe-Smith was 16 when the assault, which has left him using a wheelchair and struggling to communicate, took place last year.
Leon Rashid, 20, and Taiquane Lewis, 18, were convicted of conspiracy to murder him.
Rashid was also found guilty of having an offensive weapon.
A third defendant, Stephanie Paez-Lopez, 20, was cleared of assisting an offender by helping to get rid of a Range Rover used in the attack.
James was knocked off his bike, which he was test riding for his mother, and knifed by masked men in Brixton, south London, on 23 February 2021, jurors heard.
He video-called her from his mobile phone as he lay on the ground and he effectively died in the streets near his home before he was saved in hospital.
James was with family members at the Old Bailey to see his attackers convicted.
His mother, Lisa Bascoe-Smith, said: "James did not have any issues with anybody in the area. He is a happy boy, always smiling.
"He is into music, DJ-ing, was studying music technology and has nothing to do with the gang lifestyle.
"When I look back to the day of the incident, I remember James was so eager to help me out and make sure the bike was working.
"He wanted to look out for me. He wanted to make sure it was safe and 100% rideable.
'My phone rang and I saw James lying on the floor'
"I remember standing on my doorstep waiting for him to come back. My phone rang and I saw James lying on the floor.
"I sunk when I saw him in a pool of blood. I keep asking myself, 'How can it have happened in that space of a minute out of my eyesight?'"
Ms Bascoe-Smith said James has made some progress in his rehabilitation, adding: "He has gone from a sporty, carefree, happy-go-lucky boy to someone who has been bedridden and is struggling to move or communicate."
James's aunt, Rachel Duncan, said: "We truly need to end this cycle of violence that can often become generational. We need to eradicate knife violence on our streets."
Jurors had been told James was hit by a stolen black Range Rover in Henry Road shortly after 6pm.
'Brutal and terrible attack'
Prosecutor Edward Brown KC said: "This was a brutal and terrible attack.
"In effect, James Bascoe-Smith had died at the scene and was only brought back to life by the immediate and significant efforts of the treating medical professionals.
"However, he had suffered a significant period during which there was a lack of blood/oxygen to the brain - possibly as much as 50 minutes."
Even though there was no reason for the attack, it was "very determined and concerted" and "very nearly succeeded" in killing the teenager, Mr Brown said.
A selection of "terrifying" knives discarded by the fleeing attackers included a combat knife, a Rambo-style blade and a Zombie-style machete.
Rashid, from Thornton Heath, south London, and Lewis, of Kennington, south London, were remanded into custody to be sentenced at a later date.
Previously, a fourth defendant, Patrick Fox-Pinto, 18, from Bow, east London, was cleared of all charges after the prosecution offered no evidence.
